Your challenges

  • To qualify valve equipment for a nuclear application
  • To approve your innovative sealing solutions by having a wide range of representative conditions for water or steam tests
  • To approve your modelling through specifically instrumented tests

Our strengths

  • Installations that are unique in Europe: CYPRES (pressure cycling) and CYTHERE (thermal cycling) test resources
  • These test installations operate throughout the year (excluding statutory scheduled shutdowns every 18 months)
  • Experimental expertise backed by several decades of testing and supplemented by significant digital expertise
  • Technical excellence recognised by our internal and external customers
